Abstract: PURPOSE: To prevent a cannula from being bent or twisted, by composing the cannula of a material which is softened in a softening ratio exceeding 2:1 when the cannula is brought in touch with aqueous liquid or inserted into an organism. CONSTITUTION: This cannula structure includes a tubular cannula 12 with the peripheral end side part and a central passage part running through from the peripheral end side parts to the base end side part. The base end side part 16, 28 has inner and outer diameters larger than that of the peripheral end side part 14, 26, the thickness of the cannula 10 is made larger along from the peripheral end side part to the base end side part bringing the cannula into a form to be extended into an organism from the base end side part. The cannula 10 has a shifting part to connect the peripheral end side parts 14, 26 and the base end side parts 16, 28 and the diameter is gradually changed in the shifting area. The cannula 10 is constituted of a material to be softened in a softening ratio larger than 2:1 when it is brought in contact with aqueous liquid and/or inserted into an organism.  Thereby, the cannula has resistance effective against twisting along the whole length of the cannula structure between the point invading into a patient's body and the peripheral end side part of the hub.

Title: Tracking servo circuit
Inventor: NAKAMURA KAZUHIKO
IPC: G11B15/467
Filed: 1990-03-19
Abstract: PURPOSE:To eliminate a stationary offset occurring in tracking by adding data in an estimation circuit on speed error information or phase error information when reproduction is performed. CONSTITUTION:A comparator 10 compares a reference voltage VCC/2 in matching tracking with an ATF error signal, and issues and (H) signal when the error signal exceeds the reference voltage. A counter 11 counts the signal of the comparator 10 setting SP2' in which the reference pulse of ATF servo is delayed as a clock, and adds output on the phase error signal at an adder 12, and it is converted to a voltage value by an A/D converter 13. The speed error information is converted to the voltage value by a D/A converter 14. Three voltages are added via addition resistors R', and are supplied to a capstan motor driving circuit. When the reproduction is performed, the phase error information is increased/decreased by a count value from a midpoint value. When the tracking of a magnetic head is performed with the stationary offset. an ATF error voltage is higher than the reference voltage Vcc/2 stationarily, therefore, the counter 11 performs incremental count, and the phase error information is increased, which functions so as to negate the stationary offset.

Title: Torque control unit for nut runner
Inventor: ODA FUMITOSHI
IPC: G01L5/24
Filed: 1978-06-06
Abstract: PURPOSE: To prevent occurrence of the imperfectly clamped products and thus to enhance the working efficiency by driving the nut runner while monitoring the clamping torque and then clamping the bolt, nut and others with a proper torque.  
     CONSTITUTION: When the air is supplied to the nut runner to perform clamping of the bolt, nut and others, the output of distortion gauge 1 varies in accordance with the clamping torque. The output then undergoes A/D conversion 5 via S/H3 and is then drawn into computer 8. And when the output of S/H3 becomes larger than the output of control level setter 10, electromagnetic valve 12 and other are actuated to cut of the air supply to the nut runner. In this case, if the A/D conversion output is lower than the allowance level rage of level setter 7, the level of setter 10 is altered. Thus the operation of valve 12 and others is stopped. And the air is supplied again to the nut runner. With repetition of this action, the clamping torque can always be kept within the allowance level range.

Abstract: PURPOSE:To judge paper clogging accurately independently from a fitting error and secular change by counting paper passing time from the carrying of the paper to the detection, and changing the specified time for judging the paper clogging in response to the detected paper passing time. CONSTITUTION:A CPU 29 counts paper passing time from the detection of a recording paper sheet 18 by a sensor 25 to the detection by a sensor 26 on the basis of the detecting signal input from the sensors 25, 26 for detecting the recording paper, and detects whether the paper passing time is within a range between the specified maximum time and the specified minimum time or not to judge the generation of jam or the normal carrying. At this stage, the CPU 29 judges that the paper passing time of the recording paper sheet at the time of normal carrying is within the specified center time + or -alpha or not, and when it is within the specified center time + or -alpha, the CPU 29 changes the specified maximum time, the specified minimum time and the specified center time + or -alpha so that the obtained paper passing time becomes the center time of the specified passing time.

Title: Sealed type secondary battery
Inventor: IGAWA MICHIKO
IPC: H01M4/38
Filed: 1993-03-29
Abstract: PURPOSE:To achieve high capacity and long life by using an alloy primarily composed of zirconium and nickel, for a negative electrode, and by defining the manganese/vanadium mol ratio 1.0-2.0. CONSTITUTION:An alloy primarily composed of zirconium and nickel is used for a negative electrode. Manganese and vanadium are also contained, and the manganese/vanadium mol ratio is more than 1.0 and less than 2.0. Synergetic effect of adding both manganese and vanadium is achieved, and the effect is improved compared with a case where the single element is added. This is because a matrix of composition ratio is solidly formed, and elusion of manganese and vanadium is restricted, while formation of Zr oxide coat is hindered. The anticorrosion property in alkaline solution is improved, and the alloy used for a metal hydroxide electrode is optimized. A high capacity and long life battery is thus provided.
